Found a second problem in the same code

[Paul Tomblin <pt...@xcski.com>]

The other reason that the If-Modified-Since doesn't work is that there is a
  reqStr.append("\r\n");
before the code I mentioned before, not after it.  That puts in a
blank line, and Apache takes a blank line as an "end of the headers"
mark, so it ignores the If-Modified-Since.  Here's my diff against the
trunk:

       byte[] reqBytes= reqStr.toString().getBytes();
